RESPONSABILITÉ EST PLANIFICATION. OEdipe planificateur de la ville du présent.
2016
Il contributo analizza e individua scenari di sviluppo per una condizione particolarmente sensibile quale quella in cui i grandi valori del patrimonio culturale e paesaggistico si intrecciano con le richiesta di trasformazione. La relazione, quindi, tra la pianificazione territoriale e una visione strategicamente orientata per la valutazione delle risorse ambientali viene individuata come una possibile soluzione alla crescita senza controllo e come risolutore della condizione di conflitto determinato dalla assenza di relazioni tra tutelato e non tutelato. Le document analyse et identifie les scénarios de développement pour une condition particulièrement sensible: les grandes valeurs du pays…

Gares exurbanisées et développement urbain : Le cas des gares TGV bourguignonnes
2009
Dès la mise en service de la ligne TGV Sud-Est, au début des années 80, la Bourgogne a bénéficié de la création de deux nouvelles gares TGV, aménagées en périphérie des pôles urbains du Creusot et de Mâcon. Malgré leurs fonctions réduites, ces nouvelles gares périurbaines ont suscité d’ambitieux projets d’aménagement. De nouvelles zones d’activités ont ainsi vu le jour à proximité de ces gares. Ces projets n’ont eu toutefois que des retombées limitées en matière d’implantation d’activités économiques. Since the opening of TGV south-east railway line at the beginning of the 80s Bourgogne has profited by construction of two new stations beyond the edge of Le Creusot and Mâcon. Despite their l…

Reuse and recycling in construction: novel photocatalytic nano-mortars from valorised industrial wastes
2021
Production of novel eco-composite nano-mortars for architectural finishing, designed to combat environmental pollution affecting building shells, is reported. Specimens consist of a natural hydraulic lime mortar matrix doped with various kinds of nanophotocatalysts, produced from valorized industrial wastes: TiO2-hexaferrite from Fe3O2, and Ti(SO4)2-hydroxyapatite from Atlantic codfish bones. Samples were characterized and their photocatalytic activity was evaluated. Analysis showed that industrial wastes may be usefully reused to produce a new generation of sustainable, cheap and multifunctional novel building materials.
(progetto) Requalification du centre historique. Benevent, Italie.
2007
Violemment bombardée en 1943, la cité campanienne de Bénévent a subi l'absence de conscience historique des décideurs de l'après-guerre. Un concours d'idées national vient d'être lancé pour la valorisation du secteur le plus dégradé du centre ancien. Le projet de l'équipe lauréate - Pasquale Culotta, Riccardo Florio et Andrea Sciascia - présentait aux yeux du jury l'intérêt d'avoir appliqué le principe de la contemporanéité à des hypothèses de travail et de principes d'intervention issus d'une compréhension sensible de la morphologie, de la topographie et du lieu.
Techno-economic analysis of integrated processes for the treatment and valorisation of neutral coal mine effluents
2020
Abstract The disposal of highly-concentrated neutral coal mine effluents into the environment constitutes a severe threat to the natural ecosystem. This work proposes and compares five novel treatment chains to purify the effluent and recover raw materials. The chains present different combinations of pre-treatment and concentration technologies. In all cases, the solution sent to the concentration step is concentrated up to saturation to recover water and sodium chloride. Concerning the technical performances, the treatment chains are compared in terms of total energy demand and salt recovery. Furthermore, the economic feasibility assessment is performed via a novel global parameter, i.e. …
Influence of Operational Strategies for the Recovery of Magnesium Hydroxide from Brines at a Pilot Scale
2022
The continuous depletion of minerals caused by land mining and the increase in their demand have pushed the development of novel sustainable technological processes for mineral recovery from unconventional sources. In this context, magnesium (Mg) has gained considerable attention for its peculiar properties and high relevance of its compounds, such as magnesium hydroxide, Mg(OH)2. In the present work, the influence of several operating conditions on the Mg(OH)2 precipitation process was thoroughly investigated by adopting a novel multiple feed-plug flow reactor. The influence of (i) initial Mg2+ concentrations in the feed stream; (ii) brine and alkaline flow rates; and (iii) the product rec…
Effective magnesium recovery via seawater brines mining
In the last couple of decades, a rising interest has been focused on the research of novel and unconventional sources for mining minerals, such as industrial waste brines. As an example, brines are produced by desalination plants and discharged directly, or after being treated, into receiving water bodies possibly causing environmental concerns and renouncing the possibility to recover minerals [1,2]. Within this framework, the Water Mining WU-H2020 project aims at implementing an advanced Zero Liquid Discharge (ZLD) demo systems for the extraction of minerals and valuables products from industrial waste brines through a circular approach. The ZLD demo plant consists of: (i) Nano Filtration…
